'This invention relates to apparatus for automatically securing a slidable closure against movement when 'an attempt is made to'open the same. 1 Among the objects of this invention are to provide 'a device of the above'class which can be applied tool-removed from the clo sure without disassembling or in anyway altering the same and Without the use of the usual attaching means (such as screws, nails, or screw clamps), which when "removed leave no visible marlr siwliich securely holds "the closure against moveinent in either direction, and which'is of fewparts', simple in construction and adapted to be made and sold 'ata low price. In order that the nature 1 of my inve l ltion may be clearly understood the same described with reference to the accompanying drawings illustrating'the same, iifwhich:

Fig. 7 is a plan view of one means of connecting the engaging member to the bracket;

Fig. 8 is a perspective view showing the invention in operation;

Fig. 9 is a longitudinal sectional view showing a different form of resilient buffer.

The invention is adapted for use on any sort of sliding closure, but for the purpose of illustration is shown as applied to the lower sash A of a window. The invention comprises a bracket 9 resting upon the upper cross piece of the window sash and secured thereon in' a manner later to be described. The bracket is provided with a wedging face 10 between which and a fixed or stationary upright, which may be the side frame of the upper window sash B, an engaging member single piece of sheet suchas'the -bldck 1'1'or the'roll'er ll (Fig.2) is adapted tdbev'vedged. z

'Whilethe engaging member 11' or l1 may be of solid mate'rial' such as 'hard wood or metal with a knurled or otherwise-roughened surface; to pre'vent mutilation T of the engaged surfacefthe member preferably-is of or at 1 least'-faced i with any? suitable resilient material'whi ch will give-good frictional relSlStfifitZG fsu'ch as fii-bber -dr arubber compoundzi To force' the engaging member 11 outward-and thus 'increaseth'e hold ofthe same upon the upright a resilient buifer is interposed between the engaging member and 'thebra'ck'et 9. This resilient bufier may bee swinging'blo'ck- 12 9) piv'otedto the bracket at-12' andyieldingly forced to the limit ofits outward'movement by a spring 12 retained in'r'plac'e by a stop'pin 12 which limits the inward movement 'of the blockto a position wherein the engagingface of the block substantially-coincides .with the wedging face of the "bracket"; 'but'lthe 'bufler preferably takes theform'of 'a flat spring or tongue'l2, (Figs. '1' and 2) ;secured to the bracket adj'acent to the; top of the wedging surface 10and normally disposed -in spaced relation thereto. This resilient bufi'er is an important feature of'the invention in that it effects positive and adequate engagement of the member 11' or" 11 with the upright of a hB r is.. U27 2; I.

So ffa'r as the efficient operation of the'fastener is concerned no; connectionbetween the engaging member 1 1 o'r fl'l and'thebracket 9 is required, "bu't fo prev'ent' such member from being losti a'ndto permit it to be easily moved to and from pp'erative' position, some me'ans of connection is '-desirable,'- and this connection Ini'ay be utilized to-serve' asmeans of restraining the engaging member against retrograde movement along the wedging face of the bracket. The form;- ofconnection illustrated is that of a bail shown in plan Fig. 7. The restraining" function above noted inay be accomplished by providing elongated recesses 14 inthe opposite sides of the bracket 9' into which the pivot ends 13* of the bail 13 are received, one side of the recesses being formed with ratchet teeth 14? adapted to be successively engaged by the pivot ends 13 as the engaging member 11 ,or 11 works' down into the wedging groove. .(See FigsJl, 2, 3 and 9 also Figs. 8.)

-' Typical positions of the engaging memwithout the use of the 'us'ualattaching means such as screws, nails and clamps is proyided by a depending arm 15 having an'up'turned spur 16. The arm preferably depends from the bracket at a slightly iearward angle and h p pr ie tse rwerd d e 'u rd at an acute angle from the arm as illustrated in Figs. 1 and The bracket 9 is hooked over the top bar or toprail "of the-window, with its base resting on the bar and the arm 15 engaging the outer upright face thereof. As the engaging member llis forced downwardly into the .wedging space, bracket 9 is forced back in place on the top rail .of 019 sure It and the spur engages the outer face thereof securing a tight grip on it if the rail is of metal, and sinking into it if it is of wood. v

Altho the fastener wi.ll. .operate efficiently if the wedge face, liand the resilient abutment 12 have a substantially straight surface, I may prefer to make the same curved andto secure'quickwedging action ofthe engaging member 11 and a greater area for frictional contact; between it and the wedging surface ofthe-buacket 9. andthe opposed fixed surface by forming engaging member 11 as an eccentric wedge with curved engaging faces, the inner one 17 of which conforms substantially to the curve ofthe wedging face 10. The outer engagingsurfacel8 of the eccentric wedge may be on the same radius but from a different center.

. In the broader aspects of the invention,

the bracket 9 may be made either solid or' hollow, ofwood, metal or other suitable material formed in any desired manner and may havehe; depending-arm1l5 and the resili bu ent l2.s.ec r .-thereon- I p e- 1 fer, however,; -t o blank the entire bracket from sheet material, bending the same to the required form in :the fewest possible number of steps and thus making the ,spurred depending arm. of.the .resilientbuffer asintegral parts ofthe bracket, Such a blank before bending. is illustrated ,in Fig. ,5, the bends to be made being indicated by dotted lines. The portions of. the blank which form the sides of the bracket have lips 19 which are bent beneath the portion 20, which forms the base of the bracket thereby locking andv retaining the bracket inits final shape. For greater strength, these lips 19 may be soldered, welded; or .otherwise securely fastened to the base 20. As will be evident from Fig. 5, the portion of the blank which forms the resilient buffer or spring tongue 12 is of such width as to engage the ends of the sides of the bracket which in this modification of the invention form the wedging surface 10, of the bracket' Fig. 6 shows the bracket after BEST AVAILABLE CO? the first bending operation and Figs. 3 and f disclose the completed device. While a single spur on the depending arm might be suflicient, a plurality of spurs and a consequent better hold is produced by serrating the bottom edge of the depending arm prior to bending.
